    BHP, Rio Tinto and Caterpillar Jimblebar trial: Dynamic Energy Transfer lessons for mine planners

    June 23, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    BHP, Rio Tinto and Caterpillar are advancing a Pilbara trial of two Cat 793 XE Early Learner battery-electric haul trucks at BHP’s Jimblebar iron ore mine to Dynamic Energy Transfer testing after three months of on-site operation. The mine-site demonstration in Western Australia is focused on validating high‑payload, battery-electric haulage in production conditions and integrating dynamic charging into existing 793-class truck duty cycles. Outcomes will directly inform future trolley or in‑pit charging layouts, power distribution design and fleet transition planning for large-scale iron ore operations.

    Technical Brief

    • Two Cat 793 XE “Early Learner” units are being trialled jointly by BHP, Rio Tinto and Caterpillar.

    Our Take

    BHP’s work with Caterpillar on battery-electric haulage at the Jimblebar iron ore mine sits alongside its recent Global Framework Agreement with BOTON on intelligent conveyors, signalling that BHP is now trialling multiple decarbonisation and automation technologies across both mobile and fixed material-handling systems.

    Within our 1199 Mining stories and 2328 tag-matched pieces, iron ore items in Western Australia’s Pilbara increasingly feature OEM-led fleet trials rather than greenfield expansions, suggesting operators like BHP and Rio Tinto are prioritising productivity and emissions gains from existing assets over new capacity.

    Thiess adds fourth Liebherr R 9800 at Lake Vermont: fleet and productivity notes for engineers

    Thiess has mobilised a fourth Liebherr R 9800 hydraulic excavator to Jellinbah Group’s Lake Vermont coal mine in Queensland, expanding a fleet already built around ultra-class loading units. The R 9800, typically paired with 220–300 t class haul trucks and capable of 40–80 m³ bucket capacities depending on configuration, is being deployed to meet rising production requirements and tighten truck–shovel match. The move signals continued capital commitment to high‑productivity primary loading assets and supports longer-term planning for efficient strip mining and overburden removal.

    Finning–McCloskey 10,000th Cat engine: fleet planning notes for plant engineers

    Finning UK & Ireland has supplied its 10,000th Cat® industrial engine to McCloskey International, extending a supply partnership that began in 2006 when McCloskey established manufacturing in Northern Ireland. The engines power McCloskey’s mobile crushing, screening and material handling equipment, which is seeing rising global demand in aggregates and mining applications. For plant operators, the milestone signals long-term parts and service continuity for Cat-powered McCloskey units, an important factor in lifecycle planning and fleet standardisation.

    Glencore Sudbury INO mine rescue win: training takeaways for deep nickel operations

    Glencore’s Sudbury Integrated Nickel Operations (INO) mine rescue team has taken the 2026 Ontario Mine Rescue overall champion title in Sudbury, outperforming seven other regional winners in a province-wide final. The team completed a complex mock underground emergency scenario designed by Ontario Mine Rescue (OMR), typically involving live-fire suppression, casualty extrication and use of closed-circuit breathing apparatus under time and communication constraints. For mine operators, the result reinforces the value of rigorous, scenario-based training regimes and standardised emergency procedures across multi-level, deep nickel operations.
